Kana iwe ukashandisa Ubuntu kana chero ayo ehukama ayo echokwadi, zvirokwazvo une imwe kana zvimwe zvakamirira zvidzoreso. Canonical yakaburitsa akati wandei chengetedzo mishumo iyo inonyora dzakasiyana nenjodzi. Yekutanga yeiyi inobata akati wandei eiyo Intel's microarchitecture uye maGPU anofambidzana. Pakazara, 4 kudzvinyirira kwakagadziriswa mukati Intel microcode: iyo TSX Asynchronous Kubvisa (CVE-2019-11135), iyo Intel Processor Machine Tarisa Kanganiso (CVE-2018-12207) Uye inozivikanwa seIntel i915 mifananidzo yemidziyo yekushomeka (CVE-2019-0155 y CVE-2019-0154). Zvitatu zvekutadza kwakataurwa pamusoro zvinoonekwa sekukoshesa zvakanyanya.
Sezvatinoverenga mumishumo USN-4182-1 y USN-4182-2, masisitimu anoshanda akabatwa nehusimbe muIntel Microcode ndidzo shanduro dzese dzakanangana neUbuntu dzinofarira rutsigiro rwepamutemo uye Ubuntu 14.04, mune iyi nyaya nekuti vari muchikamu cheESM. Dzimwe dzese nenjodzi dzavakaruramisa dzakatowirirana ngoro mune tsanga Canonical's inoshanda sisitimu.
Yakagadziriswa matatu ekutanga kukanganisika muIntel Microcode
Nezve iyo kernel, Canonical yakaburitsa 4 kuchengetedzeka mishumo: iyo USN-4183-1 tsanangura 9 kudzvinyirira muUbunutu kernel 19.10, the USN-4185-1 inotiudza nezve 11 kudzvinyirira muUbuntu 18.04 uye Ubuntu 16.04, iyo USN-4186-1 Inoita gumi nembiri paUbuntu 12 uye iyo USN-4187-1 inotaura kumwe kunetseka muUbuntu 14.04. Mazhinji ekukuvadzwa aripo mumhando dzakasiyana dzeUbuntu uye nepo mazhinji ari epakati pekutanga, pane zvimwe zvekutanga kukoshesa.
Semazuva ese, Canonical yakaburitsa nhoroondo dzekuchengetedza apo Kugadziriswa kwe bug kwave kuwanikwa. Izvi zvinoreva kuti kuti tizvidzivirire kubva kumabhugi muIntel Microcode uye kumwe kushomeka muUbuntu kernel, isu tinongofanirwa kuvhura yedu software centre kana Software Gadziridza app uye shandisa mapakeji nyowani akatomirira isu. Kuti shanduko dziitwe, komputa ichada kutangwazve.
